Buffalo Bills DE Mario Williams may be asked to stand up at the line of scrimmage as a linebacker at times in 2015, according to Chris Brown of buffalobills.com. Williams is still expected to play mostly at defensive end, however.

Buffalo Bills DE Mario Williams said he hopes to build on his 14.5-sack season from a year ago in head coach Rex Ryan's defensive scheme. "Things change, personnel change, obviously coaches change," Williams said. "We pretty much just take from what we learned from (Jim) Schwartz and kind of keep it going. I mean, that's the only way you can do it in this league, because it's pretty much a revolving door."
